Final answer:
The statement that cognitive behavioral therapy and SSRI treatment together are more effective than either one alone is true for treating depression. CBT and SSRIs, when combined, generally offer a more comprehensive approach to managing depressive symptoms compared to each treatment on its own.
Step-by-step explanation:
The correct statement regarding therapy for depression is a. Cognitive behavioral therapy and SSRI treatment together are more effective than either one alone. Cognitive Behavioral Therapy (CBT) is a form of psychotherapy that has been shown to be effective in treating depression. When combined with Selective Serotonin Reuptake Inhibitors (SSRIs), which are a class of medication that increases serotonin levels in the brain, they often provide a more robust treatment than either modality alone.
While CBT on its own has been found to be quite effective and may work better than SSRIs for some individuals, it is not accurate to say it is more effective in general, as response to treatment can vary widely among patients. Regarding the statement about bipolar disorders, CBT is used within the context of a broader treatment plan, often including medication, and it's not considered the most effective stand-alone treatment option for bipolar disorder. Lastly, SSRIs can have both short-term and long-term effects on depression, so the statement that they have only short-term effects is misleading.
